IMPROVEMENT IN ROTARY CLOD-FENDERS.

Specification forming part of Letters Patent No. 94,654, dated September7, 1869.

To all whom 1t may concern:

Be it known that I, JOHN F. WOOLLEY, of Pleasant Ridge, Hamilton county,Ohio, have invented a new and useful Rotary Olod- Fender; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, making part ofthis specification.

My invention relates to a circular frame or Wheel, which runs upon thesurface of the ground, between the plow and the row of corn or otherplants, to protect the latter from injury by rolling clods or stones inthe act of plowing. 4

The first part of my improvement consists in the formation of the frameor'wheel, which has a series of concentric annular plates, connected byradial bars, whose ends project beyond the periphery of the wheel, andform spurs, by which its rotation is insured.

The second part of my improvement relates to the means of attachment andconnection with the plow-beam, which allows vertical, lateral, andlongitudinal adjustment, and is at once secure and simple inconstruction.

The drawing is a perspective view of a plow with my fender attached torun upon its right-hand side. 7

A is the plow-beam, which is embraced by a clevis having a staple-piece,B, whose ends are screw threaded to receive the nuts I), by

which the bridlepiece O is held down on the' bar I) of the frame, towhich the fender-wheel is hun At each end of the bar D is a crossbarhaving a baokwardly and downwardly extending arm, E, and an L-formedupwardly-extending arm, F. The arms B have each a series ofperforations, f, which are traversed by a screw-bolt, G, extending fromarm to arm, and forming a pivot for a bar, H, whose end is turnedhorizontally outward, forming an axle, h, for the wheel or fender. Thebar H, when the plow is upon the top of the ground, as represented inthe drawing, rests upon the horizontallyout-turned end 6 of the arm E,so as to keep the fender clear of the ground; but when the plow is inoperationthe bar is raised above the rest 0, the fender then runningupon the surface of the ground.

The fender may be made of wrought or cast metal, and has a hub,-J, fromwhich extend radial arms K, connected to annular plates L, the ends isof the radials extending beyond the outer annular plate, or theperiphery of the fender, and serving, by their hold upon the ground, toinsure the rotation of the tender as the plow is drawn forward.

The pivoted end of the axle-bar H is raised or lowered by changing thepivot-bolt G in the holes fin the arms F, and when this end of the baris raised the axle end is allowed greater depression before the barcomes in contact with the rest 0. This gives the means of verticaladjustment.

The fender-frame may be adjusted forwardly or baekwardly on the beam byloosening the nuts I) and sliding the clevis and frame along the beam.

To adjust the fender to or from the beam the nuts! are loosened, and thebar D drawn endwise between the beam and bridle-piece.

The clevis is placed diagonally or obliquely across both the beam andthe bar D, so as to prevent the backward movement of the end of theframe to which the fender is hung.

The fender may, when desired, be placed upon the other side of the plowto that shown in the drawing. In this ease the obliquity of the cleviswould be reversed, both as to the beam A and bar D, so as to prevent thebackward movement of the end to which the fender is hung, as beforestated.

It will be seen that when free access is wanted to the plow for anypurpose, such as clearing it of weeds, the fender may be raised up andthrown forward on its pivot.

1 claim herein as new and of my invention 1. The combination andarrangement,in a rotary clod-fender for plows, of two or more annularplates, L, arranged in the same plane, and straight radial arms K is,substantially as described.

2. The adjustable frame B G D E F f G, substantially as and for thepurpose stated.

In testimony of which invention I hereunto set my hand.

JOHN F. WOOLLEY.
